lol.

Oh this thread. This thread.

I'm pretty sure it could've ended 15 pages ago and we would still be in the same place.

I actually sell Amsoil products at cost to customers. In my opinion, this is a much more appealing alternative to people than becoming a preferred customer.

This is how it works:

I simply place an order with Amsoil and have it delivered to the customer. I pay the bill with my credit card, and request the funds via PayPal from the customer. That's it.

Here is an order I placed recently to give you an idea:
1 Gallon of 0W-30 Signature Series -> MSRP = $41.40
1 Absolute Efficiency Oil Filter -> MSRP = $16.90
3 Quarts of 0W-30 Signature Series -> MSRP = $31.50

As it stands, this order costs $89.80. Since I'm a dealer, I can pay for the order at cost, and have it shipped to my customer. The customer paid $69.05 for the product at cost.

I completely agree. I tell my customers to stick with factory OCI. If you absolutely must run longer intervals, you need an oil analysis first. However, I still don't recommend it.

As far as Amsoil salesmen go, I completely agree. I'm doing my best to change the stigma associated with them. I'm just an enthusiast trying to help other enthusiasts out.

So, uh... what kind of oil should I use?

:ughdance:

Oh no!! Hide everyone!!:wtf2:

Read my post under Engine & Drivetrain, "Oil Nerds Info" and then make up your own mind.

I know, I was just kidding. I've read all the info, and the engineer in me says to use the Nissan spec. The cheap bastard in me says to use a standard synthetic/semi-synthetic.

I'm no engineer, but my train of thought is that nissan spent a heck of a lot of money developing this oil, so I should probably use it. They could have gone the easy way, and contracted with mobil 1 and put it on the oil cap like on my corvette, but they must have had a reason to make their own.

I'm not an expert but have done a lot of reading on the subject the last few weeks both on this forum and on the WWW. Still learning, but for now I plan to use the Nissan Ester Oil in my 2010 roadster and I am going to try Pennzoil Platinum in my 300 ZX TT (used Pennzoil yellow/dino for almost 20 years and the car is still running great).

Regular changes and good filters may be a bigger driver rather than the brand (of several good oil brands).

Any comments on Redline? some people say its amazing some people say its not lol. but thats the same with just about everything lol.

I think that's right - Sig and Mike. If it were just a regular engine, it wouldn't bother me so much. But since this engine has some unique components, that oil is specified for a reason.

(Though I still may end up using a regular synthetic because I'm so cheap. Or maybe I'll trade back and forth.)

:happydance:

Man, it cracks me up that the "What oil should I use?" question keeps coming up. The answer, of course, is "RTFM", but here it is one more time...

The 2009 Nissan 370Z Owner's Manual just says to use a 5W-30 oil that is API certified. Here is the quote straight from the 2009 manual:

Select only engine oils that meet the American
Petroleum Institute (API) certification or International
Lubricant Standardization and Approval
Committee (ILSAC) certification and SAE viscosity
standard. These oils have the API
certification mark on the front of the container.
Oils which do not have the specified quality
label should not be used as they could cause
engine damage.

There is a one line reference to the Ester Oil in note 3 on page 9-2:

NISSAN recommends Genuine NISSAN Ester Engine Oil, which is available at a NISSAN dealer.

That's it. Note that the Ester oil is recommended, not required. Basically, use an API certified 5W-30 oil (or appropriate weight oil for your driving conditions) and change it and the oil filter at regular (reasonable) intervals, and you will be fine.

If you want to go crazy on this topic (and have many hours to kill), head on over to BobIsTheOilGuy and start reading... But be prepared for major head spinnage...

:icon17:

They have to make the disclaimer. However, as one poster stated, "Nissan developed the oil specifically for this engine". Put used french fry oil in for all I care. Just make sure it's 5W-30 fry oil.

(In Homer Simpson voice) "Mmmmmmmmm....french fries..." :p

Redline contains esters in their formula.

Nissan ester oil ~ Redline (ester) oil ~ "insert brand that contains esters" oil

Keyword is ester. So how's that for a summary of which is the "best" oil to use in your Nissan?
